AI-suggested
European organizations should implement the following specific mitigation measures: 1) Immediately review and restrict access to the workflow process builder to only trusted, necessary users with high privileges. 2) Enforce strict input validation and sanitization on all user-supplied data within workflow definitions to prevent script injection. 3) Monitor and audit workflow changes and user activities for suspicious behavior indicative of exploitation attempts. 4) Apply the latest Liferay security updates as soon as patches become available; coordinate with Liferay support for timelines if patches are not yet released. 5) Employ web application firewalls (WAFs) with custom rules to detect and block typical XSS payloads targeting workflow components. 6) Educate privileged users about the risks of XSS and the importance of cautious input handling. 7) Implement multi-factor authentication (MFA) to reduce the risk of compromised credentials being used to exploit this vulnerability. 8) Regularly back up workflow configurations and portal data to enable recovery in case of compromise. These targeted actions go beyond generic advice by focusing on the specific attack vector and affected components.
Description
Cross-site scripting (XSS) vulnerability in workflow process builder in Liferay Portal 7.4.3.21 through 7.4.3.111, and Liferay DXP 2023.Q4.0 through 2023.Q4.5, 2023.Q3.1 through 2023.Q3.8, and 7.4 update 21 through update 92 allows remote authenticated attackers to inject arbitrary web script or HTML via the crafted input in a workflow definition.
